Eur. J. Nutr. 53, 1051–1064. Association of dietary type with fecal microbiota in vegetarians and omnivores in Slovenia 2014

Bogovič, B. M., Obermjer, T., Lipoglavšek, L, Grabnar, I., Avguštin, G. and Rogelj, I.

Notes: The authors of this study used real time-qPCR and PCR-DGGE (denaturing gradient gel electrophoresis) to analyze and compare the mixed bacterial systems from fecal samples of vegetarians and omnivores. Bacterial DNA was isolated from frozen fecal samples using the Maxwell® 16 Tissue DNA Purification Kit, and PCR-DGGE reactions were set up using GoTaq® Flexi DNA Polymerase and GoTaq® Flexi Colorless Reaction Buffer. The authors of this study were able to detect differences in microbiota that seemed to be related to diet. (4523)

Folia Microbiol. 58, 623–30. Detection and quantification of probiotic strain Lactobacillus gasseri K7 in faecal samples by targeting bacteriocin genes. 2013

Treven, P., Turkova, K., Trmčić, A., Obermajer, T., Rogelj, I. and Matijašić, B.B.

Notes: The authors were interested in quantitating the presence as well as the prevalence of Lactobacillus gasseri K7 in humans that did not consume the probiotic bacteria. Fecal samples from 45 healthy adults were collected, frozen, diluted, centrifuged and digested with proteases. After sonication, DNA was extracted using the Maxwell® 16 Tissue DNA Purification kit on the Maxwell® 16 instrument. This same kit and instrument also were used to isolate bacterial DNA from 1ml bacterial cultures. The purified DNA was PCR amplified using primers for gassericin K7 A and K7 B (bacteriocin) genes and GoTaq® Flexi DNA Polymerase in Green GoTaq® Flexi Buffer for 30 cycles. PCR products were analyzed by 1.8 % agarose gel electrophoresis. (4522)

Food Control 23, 400-404. Development and validation of fast Real-Time PCR assays for species identification in raw and cooked meat mixtures. 2012

Cammà, C., Di Domenico, M., and Monaco, F.

Notes: These authors used the Maxwell® 16 Tissue DNA Purification Kit to extract DNA from 200µl samples of raw meat homogenate from beef, pork, poultry and lamb samples. They also used the Wizard® Genomic DNA Isolation System to extract DNA from cooked meat samples. The extracted DNA was used in real-time, quantitative PCR assays to identify species-specific DNA spiked at 1% in mixed DNA samples. (4353)

Ann. Oncol. 20, 879-884. The importance of KRAS mutations and EGF61A>G polymorphism to the effect of cetuximab and irinotecan in metastatic colorectal cancer. 2009

Garm Spindler, K.L., Pallisgaard ,N., Rasmussen, A.A., Lindebjerg, J., Andersen, R.F., Crüger, D., and Jakobsen, A.

Notes: These authors used the Maxwell® 16 System to isolate genomic DNA from whole blood and normal colonic tissue samples. The DNA was used in genotype analysis, testing for wildtype and mutant KRAS genes, and for various EGFR-related polymorphisms. The results were used in a research study testing the relationship between various genotypes and response to different treatment regimens. (3961)
